In this instance, in order to obtain the eTA number, the individuals should submit a case-specific enquiry form to Immigration, Refugees and Citizenship Canada (IRCC) explaining the situation. An email response from IRCC will contain the eTA number.

Individuals who find themselves in this situation, or who simply wish to re-apply for a new eTA, may do so at any time. Once the more recent eTA is approved, it will replace the one that already exists. If the individual applies for another eTA, but on a different passport, that eTA - once approved - would not replace the one that already exists; it would be tied to the second passport, which the individual could use when travelling to Canada by air. In either case, the system will not prevent the individual from proceeding.

Reasons for refusal may be for prior criminality or for medical reasons. In terms of criminal inadmissibility, something as seemingly minor as an old DUI (Driving Under the Influence) going back a number of years can result in being rejected. Even if the crime was minor in nature, and even if the person's criminal record has been clean since it took place, Canada still has the right to deny entry. Some examples of convictions that could make you inadmissible to Canada include: DWAI, Theft, Petty Theft/Larceny, Assault, Drunk & Disorderly Conduct, Obstruction of Justice, Possession of marijuana, cocaine or other controlled…

Citizens of eTA-required (i.e. TRV-exempt) countries who are refused an eTA may be issued a temporary resident permit depending on the nature and circumstances of the inadmissibility and the continuing rationale for travel. The visa office responsible for the applicant's country may have its own application form for temporary resident permits. Applicants should check the visa office to find out about its specific application procedures.

The eTA system mirrors the current U.S. Electronic System for Travel Authorization (ESTA) program, and is very similar to it in a number of ways. The governments of Canada and the U.S. have stated that eTA and ESTA systems form a common approach to screening travellers outside the North American perimeter.

No. All travellers from eTA-required countries, regardless of their age, need an eTA when they fly to Canada.

Records of a previous entry to Canada will not trigger secondary examination, unless those records contain adverse information to that enter in the application for an eTA.

Visa-exempt foreign nationals who have been issued a Confirmation of Permanent Residence (COPR) document also receives an electronic authorization to travel to Canada and, therefore, does not need an eTA. This process is not visible to these individuals, and they do not need to print out any additional information. They will, however, need to travel to Canada with their valid passport and valid Confirmation of Permanent Residence document.

Citizens of Mexico will be able to apply for an eTA as of December 1, 2016. There is no confirmed date yet for eTA expansion for Brazil, Bulgaria, or Romania, however, it is expected to be implemented only after eTA is fully implemented for citizens who do not need a visa to come to Canada. Until then, citizens from Brazil, Bulgaria, and Romania still need a Temporary Resident Visa (TRV) to travel to Canada.
